Application filed March 2a, 1912. Serial No. easy 7e.

To all whom it may concern Be it known that I, ,WAL'rnn BLAKE, a citizenof the United States, and a resident of the city of Appleton, county ofOutagamie, and State of Wisconsin, have invented certain new and usefulImprovements in Non-Freezing Silos, of which the following is aspecification.

My invention relates to silos, and the object of my improvementis toprovide a frostproof silo of the construction hereinafter described.

The invention consists in the combinations and' arrangements of partshereinafter described and claimed. The invention will be best understoodby reference to the accompanying drawini forming a part of thisspecification, and in which 1 Figurel is a sectional view of a silobuilt in'accordance with my invention, taken on line 1-l in Fig. 2, Fig.2 is a part sectional elevation of the same, Fig. is a fragmentalvertica section showing the method of spacing the walls apart, Fig. is afragmental cross section -of the wall showing the rod reinforcements,and Fig. 5 is a similar view showing a modification of my invention.

Similar numerals of reference indicate imilar parts throughout theseveral figures.

The preferred form of construction, as illustrated in the drawing.comprises an inner wall 6 and an outer wall 7 supported on a base 8.Both said inner wall and outer ,wall are extended to form roof portions6" and 7. of the building and are spaced apart to form a free air space9 therebetween. Saidwalls are provided with a door-opening 10 and saidroof portions are provided with a'ventilator opening-11. In saidventilator opening is formed a ventilator 12. The edges of said wallsare joined at said ventilator opening by means of a filler 1.3

is so desired, metallic coverings 21 and 22,

as indicated in Fig. 5, may also be provided on the inner side of theinner wall and the outside of the outer wall. The metallic coverings l9and 20 are rigidly spaced apart by means of a plurality of tie rods 23,which are threaded and fitted with. clamping nuts :24 to form a rigidconnection.

Inclosed in the walls 6 and 7 and the roof portions 6' and 7, are aplurality of rods 25 spaced apart to reinforce said Walls and roofportions. Also inclosed in such walls and roof port-ions are the rodreinforce ments 26 placed in vertical position. Supporting members 27are preferably provided with eyes 28 through which the rods 26 areplaced. Such supports 27 may be made, as indicated in Big. a, with theeyes 28 in their central portions and provided with irregular ends .29on one end and their other end portions extended through the metalliclinings on the walls 6 and 7, or the end por tions of such supports maybe provided with screw-threads and nuts threaded on, as indicated at 30in Fig With this construction a frost-proof building is constructed ofvery rigid and (1111 8. ble construction.

While .l have illustrated. and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention.

ering on the outer side of said inner Wall;

l'lllTfi-tlilbtl bolts extending between and through the coveringsonsaid inner wall and said outer wall; nuts threaded on said bolts spacingsaid walls apart; vertical reinforcing rods in said walls; transverserods in said Walls, each transverse rod having] one of its ends securedin one of said coverings and an eye in its intermediate portion andsecured on one. of said vertical 'relnforcing rods; and horizontalreinforcing rodsm said walls and restlng on said transverse rods,substantially as descrlbed.
